In an ideal world I'd love to see a World Cup similar to that of football or rugby union. A tournament in one country over a couple of weeks, two team matches, but unfortunately that would cause too many mismatches. Football can get away with for e.g. Italy v New Zealand in the 2010 World Cup but can you imagine Poland v Hungary or Slovakia at speedway?
Maybe a divisional type of tournament? Have matches between Poland / Australia / Sweden / Denmark / GB / Russia? in division one, Czech Republic, Germany, USA, Slovenia, Finland, Italy in division two? promotion / relegation?
Having said all that the run off and final this year were extraordinary. The level of skill was a big step up from that seen at league level week in week out. It is a big step up for a lot of riders and this is where I feel the British riders miss out by not being exposed to this sort of level of intensity more often. How many riders did we see this week riding above themselves because they were riding for their county? Anybody watching the sport this week had to be impressed.
